Hi,
This is probably a newbie question but I couldn't google the solution.
If I try to serialize a List<WhateverType> using the writeObject()
method in the HessianOutput class, it throws an IllegalStateException
complaining that my WhateverType should be serializable (I've attached
a stack trace at the bottom).
By stepping through the code, it is apparent why this occurs, but I
find this a little bit counterintuitive - if Hessian defines the
binary encoding of arbitrary types, why do I need to use the Java
built in Serialization mechanism?
Surely this makes the List useless for cross-language purposes?
Or am I missing the point here?
Any help is appreciated,
Ben
